About Leaf Wetness Sensors
There are three leaf-wetness sensors classifications:
- Surface contact types that measure the electrical resistance of a water film on the leaf surface,
- Mechanical types that detect a change in sensor length or weight, or
- Electrical resistance types that are applied to mock leaves and are designed to emulate periods of leaf wetness after rainfall, dew, or spray.
